Peanut-shaped bulges are evident in about 45% of edge-on galaxies. These are thought to form via bar-driven secular evolution. Since bars cannot be seen directly in edge-on galaxies, various kinematic diagnostics of bars have been developed over the past 10 years. It now appears well established that bars are present in a majority of these systems. However, an edge-on view is ill-suited to studying the relation of peanuts and bars in greater detail. I discuss the stellar kinematic signatures of peanuts in face-on systems, including when bulges form through other than secular evolution. Future observations can search for peanuts in face-on systems to test theoretical expectations, and will help also distinguish between bulge-formation mechanisms. I also demonstrate how such observations may be modeled in the future by considering a novel dynamical modeling technology applied to the bulge of the Milky Way. |
